SHEET 5 BF 5 FIGS 1 GARAGE FOR THE STORAGE OF VEHICLES This is a divisional, of application Ser. No. 883,903, filed Dec. 10, 1969. Now U.S. Pat. No. 3,688,922 issued Sept. 5, 1972.

BACKGROUND 1. Field of the Invention This invention relates to garages for the storage of a multiplicity of vehicles above one another in superimposed or stacked condition, such garages comprising a plurality of superimposed, tiltable and intercoupled platforms which can be alternatively placed in communication with a common run-on or approach area.

2. Description of Prior Art A garage of this kind is known having two platforms which are coupled by parallel links which are arranged substantially vertically. Each platform affords room for one vehicle, and one platform or the other can be placed in communication with the approach area by raising or lowering the end of the platform nearest this area.

It is clear that where the two platforms have a parallel guide system the inclination of the two platforms into the drive-on position for one of the platforms is determined by the ratio between the clear height and the length of the platform. It is apparent that the inclination of the platforms in this situation is comparatively large. The result of this large inclination of the platforms is that frequently there is a danger that a vehicle will collide with the platform or with the bottom of the approach area when it is being driven on or off.

To avoid this the attempt has been made not to guide the two platforms in parallel fashion but to prescribe arrangements which allows slight lifting and lowering movements to the lower platform at least. The possibilities afforded by this are however limited because account must be taken of differing vehicle dimensions. Moreover suchconstructions are of increased cost and, in some circumstances, supervision requires particular care and attention which cannot always be counted on.

The object of the invention has been to provide a garage for the purpose stated above which is typified by a particularly simple and practical construction and in which there will be no difficulty involved in driving on to or driving off of the platforms. A further object of the invention lies in devising the arrangement in such a way as to ensure the accessibility of every parked vehicle.

SUMMARY OF THE INVENTION The invention relates to a garage of the kind stated above and is characterised by the facts that the platforms are each of a length sufficient to accommodate at least two vehicles, that an approach area is provided at each of the two ends of the platforms, and that in one tilted condition of the platforms an upper platform communicates with one approach area and a lower A platform with the other approach area, whilst in the form and equips the garage with two approach areas. To do this, however, the invention does not simply duplicate the basic requirements or dimensions of the garage but provides a simple solution to the problems set forth above in an unexpected way. Thus if a platform is madeof a length sufficient to accommodate at least two vehicles end-to-end, a comparatively small amount of tilting will suffice to bring into communication with an approach area a platform located above or below the platform previously in communication with this approach area. There is no drive-on problem. The fact that the invention provides for two approach areas further caters for ready accessibility to any vehicle or to any parking place. Two parking places are directly accessible for every inclination of the platforms and two other parking places for the other tilted position thereof.

The combination of at least four parking places in a garage with a single operating unit and so on further involves a considerable simplification in the amount of construction required, as related to one parking area.

In the invention the platforms can be rigidly connected together, but it is also possible to implement the coupling by a pivotable linkage arrangement. In accordance with a further feature of the invention it is provided that the angle of tilt is arranged substantially symmetrically in relation to the planes of the platforms.

In the case of three platforms arranged one above another the tilt shaft is arranged substantially at the level of the middle platform, and in the case of two superimposed platforms substantially at half the heightwise distance between these platforms.

A particularly favourable construction is achieved by disposing the tilt shaft beneath the lower platform. Instead of a construction having one journal or the like, use may advantageously be made of a double-linkage arrangement, in which the upper ends of the links are at a shorter distance apart than the lower ends. In this way there will be a linkage pole in the area between the platforms and thus similar motions to those produced where a rigid tilt shaft is used.

The invention also proposes further arrangements for raising and lowering the tilt shaft or shafts of the platforms. Even if it is per se possible to provide, for example, threeplatforms andthree different angles of inclination of these platforms to make, them all accessible, it is preferable, when there are more than two platforms arranged one above the other, to raise the platforms and the associated tilt shaft or shafts. A favourable arrangement is for example obtained if more than two platforms are rigidly interconnected and the common tilt shaft is arranged to be adjustable heightwise. In an upper position of the tilt shaft the middle and lower platform are accessible at each time, and in the lower position of the tilt shaft the upper and middle platforms are accessible. An arrangement of this sort is particularly suitable in cases where it is required to combine long duration parking places with temporary parking places.

A very advantageous arrangement according tothe invention comprises a plurality of platforms which are interconnected by links and are carried by two reciprocable drive units, which latter are used both to produce the tilting and the reciprocating movements. These reciprocable drive units, which may for example comprise piston-cylinder assemblies or even draw cables or chain drives or the like, are preferably arranged in the vicinity of the ends of the platforms.

In accordance with a further feature of the invention guides for the'reciprocating and tilting movements are vantage that there is a secure support for the'complete assembly despite the provision for heightwise adjustment and tilting of the platforms in each operative position. In particular the maximum permissible inclination of the platforms cannot be exceeded, even should some defect occur, for example in the reciprocable drive means. The guide means prescribed also simplifies the operation of the system. If for example the drive is arrested at one end of the platforms, the drive at the other end can straight away be operated so that the ends of three different platforms can be coupled to the appropriate approach or access area as required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the garage illustrated in FIG. 1 a bearing block 29 is provided in a pit 28, this block carrying a shaft 10 which supports two tiltable platforms 1 and 2 rigidly connected to one another. The approach areas are here designated 7 and 8 and the vehicles which are parked on the platforms 1 and 2 are identified at 9. It is clear that in the situationillustrated in FIG; 1 the righthand parking area is accessible from the upper platform 1 and the left hand parking area from the lower platform 2.

FIG. 2 shows the situation which is brought about by pivoting the platforms by means of a fluid cylinder 30, and in which the communication between the platforms and parking areas is reversed.

Whilst in the embodiment illustrated in FIGS. 1 and 2 the tilt shaft is arranged between the two platforms 1 and 2, in the example illustrated in FIGS. 3 and 4 this shaft 11 is disposed beneath the lower platform.

If, as illustrated in FIGS. 3 and 4, the platforms 1 and 2 are of the same length it is advisable to provide the approach areas with projecting portions 31 where they fringe the pit 28.

The modification illustrated in FIGS. 5 and 6 includes. a linkage system, comprising links 13 and 14, disposed beneath platform 2. The ends 15 of the links which support the two platforms 1 and 2 are at a smaller distance apart than the lower ends 16 of these links.

In the embodiment illustrated in FIGS. 7 and 8 three platforms 3 are arranged one above the other and are rigidly connected together. The tilt shaft is designated 12 and this can be adjusted heightwise by a reciprocable drive unit 17 constituted by a fluid cylinder, so that at any time either the two upper (FIG. 7) or the two lower (FIG. 8) platforms are accessible.

The foregoing examples which have been illustrated are concerned with platforms rigidly coupled together, but FIGS. 9 and 10 show platforms 4 which are intercoupled by links 20 and 21 which are pivotally connected to these platforms. Link 20 is supported by the reciprocable drive unit 18 and link 21 by the reciprocable drive unit 19. By differential heightwise adjustment and variation of the inclinations of the platforms 4, any desired parking area, that is to say either end S or 6 of any of the platforms 4, can be placed in communication with the approach area 7 or the approach area 8 respectively.

The provision for adjustment of the platforms, both heightwise and in terms of inclination, requires a particular guide system which, in accordance with the invention is constituted by guideways 22 and 23 at the forward and rear ends of the platforms 4. Each of these guideways comprises a channel-section rail 27 in which elements 24 engage. As can be seen from FIG. 11, when the inclination is at a maximum the guide element 24 bears against the limb 25 of the rail, whilst in the horizontal disposition of platforms 4 (not shown) the guide element 24 would bear against the other limb 26 of this rail. It will be understood that the distances between the two lirnbs 25 and 26 must be appropriately chosen in the same way as the mutual association of the two guideways 22 and 23.
